The fastest basal metabolic rate (BMR) is exhibited by normalrat. In normal rat the pituitary gland or the thyroid gland are notremoved and hence will exhibit the highest basal metabolicrate. The basal metabolic rate is slower in thyroidectomised rats ascompared to the normal rat. The thyroid hormone helps maintainmetabolism and body heat. Since the thyroid gland is removed thethyroidectomised rat the basal metabolic rate will be was slower.However, normal rat has greater basal metabolic rate because itpossess the glands that are necessary to stimulate and control therelease of thyroid hormones. If an animal has been thyroidectomised, the two hormones thatwould be missing for its blood is triiodythronine andthyroxine. If an animal has been hypophysectomised, the hormone that wouldbe missing for its blood is thyroid stimulating hormone (TSH)because of the missing pituitary gland. The normal rat was hyperthyroidic since the thyroxine injectionsleads to an increase in the metabolic rate. However, it did notlead to the development of goiter. The thyroxine injection has resulted in the increase of basalmetabolic rate (BMR) on the rat. However the BMR was still on thelower side in comparison to the basal metabolic rate seen in thecase of normal rats with thyroxine. One reason can be attributed tothe low dosage of the thyroxine injection. The administration of thyroxine injections on thehypophysectomized rat resulted in increased basal metabolic rate(BMR). However the BMR was still on the lower side in comparison tothe basal metabolic rate seen in the case of normal rats withthyroxine. One reason can be attributed to the low dosage of thethyroxine injection. The administration of thyroid-stimulating hormone (TSH) into thenormal rat will also result in the increase of basal me Continue reading >>

Here are 10 factors that affect bmr and metabolism: 1 body size - people with bigger bodies tend to have a larger bmr because they usually have larger internal organs and fluid the 'rat runs' drivers use to avoid m4 toll. Bmr is the main way humans spend energy, and is dependent on thyroid respiration rates of hepatocytes from rats of different thyroid status,. Basal metabolic rate (bmr) is the rate of energy expenditure per unit time by endothermic animals at rest it is reported in energy units per unit time ranging from. What was the effect of thyroxine injections on the thyroidectomized rat's bmr how does the bmr in this case compare with the normal rat's bmr was the. The concept of basal metabolic rate (bmr) was developed to compare the metabolic rats, cattle, and humans, the respective values are 09, 082, and 104. Distribution of tumors in female bd-iv rats treated orally with chloroprene benchmark modeling results for olfactory atrophy in male f344/n rats (bmr . Decline in bmr with age has also been reported in rats (greenberg, 1999 even et al, 2001 miyasaka et al, 2003) and dogs (speakman et al, 2003) however. Experiment results predict question: predict question 1: make a prediction about the basal metabolic rate (bmr) of the remaining rats. Stress and body weight changes variations in food and water consumption, urine volume, and bmr were also observed twelve rats were subjected to tone. Basal metabolic rate of post-metamorphic xenopus laevis indeed, in rats other thyroid hormones have exhibited extended effects on. Here's how to do the bmr calculation manually take your lean weight and multiply by 115 for men, or 120 for women that gives you a typical overall body.

3 If an animal has been thyroidectomized, what hormone(s) would be missing in its blood? Triiodothyronine and thyroxine. 4 If an animal has been hypophysectomized, what effect would you expect to see in the hormone levels in its body? For the hypophysectomized rat, TSH would be missing due to the missing pituitary gland. 5 What was the effect of thyroxine injections on the normal rats BMR? The levels were a little off. The normal rat was hyperthyroidic because the thyroxine increases the metabolic rate but it did not develop a goiter. 6 What was the effect of thyroxine injections on the thyroidectomized rats BMR? How does the BMR in this case compare with the normal rats BMR? Was the dose of thyroxine in the syringe too large, too small, or just right? The BMR increased for the thyroidectomized rat with the thyroxine injections. The BMR was still a little bit under the normal rats BMR with thyroxine. The dose was too low. 7 What was the effect of thyroxine injections on the hypophysectomized rats BMR? How does the BMR in this case compare with the normal rats BMR?

Activity 1 Metabolism and Thyroid Hormone 1 Which rat had the fastest basal metabolic rate (BMR)? 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction? ___ The BMRs differed because the surgically altered rats were missing either the Pituitary or Thryoid gland that release thyroid hormones. 3 If an animal has been thyroidectomized, what hormone(s) would be missing in its blood? The animal will be missing trioodythronine and thyroxine. 3.

Which rat had the fastest basal metabolic rate (BMR)? Why did the BMR's differ between the normal rat and the surgically altered rats? The other 2 rats had either had the thyroid or pituitary gland surgically removed. This plays an important part in hormone secretion to raise or lower BMR. If an animal had been thyroidectomized, what hormone(s) would be missing in its blood? If an animal had been hypophysectomized, what effect(s) would you expect to see in the hormone levels in its blood and in its BMR? The metabolic rate would go down with no pituitary gland to produce THS What was the effect of thyroxine injections on the normal rat's BMR? The metabolic rate increased to 2000, which was higher than the baseline What was the effect of thyroxine injections on the thyroidectomized rat's BMR? How does the BMR in this case compare with the normal rat's BMR? Was the dose of thyroxine in the syringe too large, too small, or just right? The metabolic rate was increased to 1910 which was not as high as the baseline. Metabolic rates were raised to reach normal rates, even though still lower than baseline.

The normal rat had the faster basal metabolic rate, because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction? The normal rat has the highest BMR because it has the glands required to stimulate and regulate the release of thyroid hormones. 3 If an animal has been thyroidectomized, what hormone(s) would be missing in its blood? The effect of TSH was to increase the normal rat's BMR 9 What was the effect of TSH injections on the thyroidectomized rats BMR? How does the BMR in this case compare with the normal rats BMR? Why was this effect observed? There was no effect on the thyroidectomized rat's BMR with the injection of TSH because there was no thyroid gland to stimulate. 10 What was the effect of TSH injections on the hypophysectomized rats BMR?

WHICH RAT HAD THE HASTEST BASELINE METABOLIC RATE? THE THYROIDECTOMIZED RATS BMR WAS SLOWER THEN THE NORMAL RAT. THE HORMONE OF THE THYROID GLAND HELPS MAINTAIN METABOLISM AND BODY HEAT SINCE THE THYROID GLAND IS REMOVED THE RAT COULDNT DO THAT AND ITS BMR WAS SLOWER. COMPARE THE BASELINE METABOLIC RATES FOR THE THYROIDECTOMIZED RAT AND THE MORNAL RAT AND EXPLAIN YOUR RESULTS. THE HYPOPHYSECTOMIZED RATS BMR WAS SLOWER THEN THE NORMAL RAT. THIS SI BECAUSE THE PITUITARY GLAND HAS BEEN REMOVED. PITUITARY GLAND SECRETES TSH THAT CONTROLS PRODUCTION AND RELEASE OF THYROXINE, WITHOUT IT THE METABOLIC RATE IS EFFECTED AND IS SLOWER. COMPARE THE BASELINE METABOLIC RATES FOR THE HYPOPHYSECTOMIZED RAT AND THE NORMAL RATAND EXPLAIN YOUR RESULTS. THE THYROXINE MADE THE RATS METABOLIC RATES VERY CLOSELY SIMILIAR.
